摘要： An air/fuel ratio control system is applicable to lean mixture combustion internal combustion engines. The control system determines the value of the mixture ratio at which engine stability can switch between stable and unstable conditions. As long as the engine continues to run in a stable condition in which the engine roughness is within an acceptable range, the mixture is intermittently leaned out by a given proportion. On the other hand, when engine roughness in an unacceptable range is detected, the mixture ratio is enriched by a given proportion to overcome the unacceptable engine roughness. Enrichment of the mixture is continued until engine roughness within the acceptable range is detected.

摘要： Normally, an air-fuel ratio is controlled in accordance with the engine speed and the intake air quantity of an internal combustion engine with a turbocharger. When the output pressure of the turbocharger increases excessively, an intake relief valve opens to decrease the intake air quantity. In this case, the fuel injection quantity is controlled solely in accordance with the engine speed.

摘要： An air fuel ratio control system includes a correction system for correcting air/fuel ratio depending on measured atmospheric air pressure. The correction system has sensors for detecting engine operating conditions. A reference intake manifold pressure corresponding to the detected engine operating condition at sea level is obtained from the engine operating condition. The reference atmospheric air pressure is compared with the measure intake manifold absolute pressure to determine a difference value. Based on the difference, a correction value for controlling the air/fuel ratio is determined.

摘要： A running state control system for a motor vehicle comprises engine output torque control means, shift detecting means, and a valve timing control system (VTC). When detecting a shifting, the shift detecting means outputs a torque cutoff command signal to the engine output torque control means so as to actuate the valve timing control system. An opening timing of intake valves is changed thereby in a direction such to decrease an engine output torque. In another aspect of the invention control is exercised over a braking torque applied to the driving wheels of the vehicle in correspondence with a traction loss or skid detected thereat.
